First of all, to be fair to the Experts:
Two Separate Questions = Two Posts.
To Answer the First Question:
Firstly, what's the easiest way to stop people using email on their browser e.g. gmail, hotmail etc. From what I understand products like Barbedwire Minesweeper will do this. Is there a better way or better product?
How many people are we talking about here? Just a Handfull or a large Organization.
If its a handful then the easiest way would be to just edit the HOSTS file on the individual PC to block the site.
Here is a good article on it and how to use it:
